It’s not the resolution at this point. Recent Games with performance mode are running them at below 1080p and still can’t hold 60fps.I'm always confused why they push 4k so much. I would always select the 1440/60 option if given the chance. It hits the sweet spot for me. Another one that I've seen some insomniac games do is the 4k/40 option and use VRR to stabilize it.
It’s basically like, If you want last gen graphics and gameplay you can have 60fps. If you want advances in graphics and tech, the games are probably not gonna be 60fps on consoles.
